Article Introduction：There are a variety of attack methods that can take a website offline, and the more complex methods involve technical knowledge of databases and programming. A simpler method is called a "DenialOfService" (DOS) attack. The name of this attack method comes from its intention: to cause normal service requests from ordinary customers or website visitors to be denied. Generally speaking, there are two forms of DOS attacks: the third and fourth layers of the OSI model, that is, the network layer attack. The seventh layer of the OSI model, that is, the application layer attack. The first type of DOS attack - the network layer, occurs when a large number of of junk traffic flows to the web server. When spam traffic exceeds the network's ability to handle it, the website goes down. The second type of DOS attack is at the application layer and uses combined

Article Introduction：PHP uses a generational garbage collector to automatically reclaim memory through reference counting and mark sweep. PHP keeps track of the number of references pointing to a variable, and when the reference count reaches 0, the variable is considered no longer in use. PHP marks all reachable objects starting from the root node, and unmarked objects will be cleared to free up memory. Manual memory management techniques include explicitly destroying variables using unset(), avoiding reference cycles, and using weak references.

Article Introduction：Table 3-4 Common parameters related to garbage collection plus memory allocation of -XX:+UseSerialGC objects. Conceptually, they should all be allocated on the heap (in fact, they may be disassembled into scalar types after just-in-time compilation and Indirectly allocated on the stack [1]). Under the classic generation design, new objects are usually allocated in the young generation. In rare cases (for example, the object size exceeds a certain threshold), they may also be allocated directly in the old generation. The rules for object allocation are not fixed. The "Java Virtual Machine Specification" does not stipulate the creation and storage details of new objects. This depends on which garbage collector the virtual machine is currently using and the memory-related functions in the virtual machine. Parameter settings. Objects are allocated first in Eden in most cases

Article Introduction：Face recognition is a technology that uses computer vision technology to automatically recognize faces. Face recognition algorithm based on deep learning is one of the most advanced technologies, which achieves accurate face recognition by learning a large number of face images. Types of face recognition algorithms based on deep learning Face recognition algorithms based on deep learning can be divided into two categories: feature-based methods and feature learning-based methods. Feature-based face recognition methods rely on hand-designed feature extractors to extract feature vectors of faces, and then use classifiers to classify these feature vectors to achieve face recognition functions. Common feature extractors include local binary pattern (LBP), principal component analysis (PCA), and linear discriminant analysis (LDA). However, these methods have some drawbacks. first

Article Introduction：Different from traditional object detection problems, few-shot object detection (FSOD) assumes that we have many basic class samples but only a small number of novel class samples. The goal is to study how to transfer knowledge from basic classes to novel classes, thereby improving the detector's ability to recognize novel classes. FSOD usually follows a two-stage training paradigm. In the first stage, the detector is trained using rich base class samples to learn the common representations required for object detection tasks, such as object localization and classification. In the second stage, the detector is fine-tuned using only a small number (e.g. 1, 2, 3...) of novel class samples. However, due to the imbalance in the number of basic class and novel class samples, the model learned is usually biased towards the basic class, which leads to the novel class target being different from the similar basic class.
